Cruise is much better than I am at maintaining a low cruise speed, e.g. 65mph, whereas without it I get bored and speed up, usually averaging low 70s. That 65mph long distance cruise is how I got my best ever economy out of my car.
There are lots of reasons and circumstances in which it's worse or costs fuel, too, of course.

I could and sometimes just switch it back on depending on how much speed has dropped if too much speed has dropped the re-acceleration rate may be more than I want for smoothness. For overtakes my CC will allow me to accelerate and if I then lift off the car goes back to the set CC speed.

Oh, one final thing: this was on BP normal diesel. It seems to be good stuff.
Best wishes all,

Some French crap.

While that may be true if the road is flat, I'm not sure it's still true once you start going up and down a few hills.

In my eyes, when you're driving on the motorway and there are a few gradients, it's probably more economical to build up speed going downhill, and be a bit more light-footed whilst going up hill.
This may cause the speed of your vehicle to vary between 60 and 80 (depending on car blah blah), but someone with CC switched on at 70 would use more fuel as the car would open the throttle to maintain 70 going uphill, and close off the throttle to maintain 70 going downhill, resulting in the car gaining no extra momentum on the downhill bits that can be burnt off on the uphill bits.
Horse wrote: The m-way I regularly use is M4 J13-10 and, of that, J13-12 is hardly flat (ish). Since using CC to maintain constant speed would adversely affect fuel consumption, I'll often knock the speed down a tad then back up for the downhill and flatter sections.
